Hi there

just had Sky Q delivered, and have the Sky Q Hub and th Sky Q TV Box. The hub and the box are in different rooms, so cannot Ethernet.

I'm wanting to get 3 Deco M5s. I'll do three things:

1) Ethernet one into the Hub router (and turn the router's WiFi off).  
2) Ethernet another into the TV Box (and turn the TV box wifi off)

3) Put the 3rd one upstairs somewhere.

Would this work? Would I need to turn the wifi off the TV box and Ethernet the Deco in Step 2?

I've read a tonne of forums on this but keep getting stuck... really appreciate any guidance before purchasing the M5.

Also, if this would work, should I get a different router from the Sky Q, or will the M5s do all the hard work (I.e device traffic management etc)
